Definitions

  • the present invention relates to a mould for manufacturing a floor part or wall part as a construction element with a sandwich structure comprising a plurality of layers.
  • the invention further relates to a system for manufacturing a floor part or wall part with a sandwich structure comprising a plurality of layers, and a method for manufacturing a floor part or wall part with a sandwich structure comprising a plurality of layers.
  • Homes are often provided with a floor part or wall part with a so-called sandwich structure comprising a plurality of layers.
  • a wall part can for instance comprise a first (lower) concrete layer, a (middle) insulating layer and a second (upper) concrete layer.
  • first and second concrete layers and the insulating layer different sizes, i.e. to provide them with different dimensions in respect of length and width. It can thus be desirable to make the dimensions of the concrete layer smaller or greater than the insulating layer and second concrete layer. This results in the first concrete layer being offset respectively inward or outward relative to the insulating layer and the second concrete layer.
  • Devices known in practice for making floor parts or wall parts with a sandwich structure are provided with a number of mould elements, which are optionally provided with an inward offset profile for the purpose of realizing a first concrete layer with smaller dimensions, wherein the mould elements are placed adjacently of each other by means of a so-called windmill sail construction.
  • the windmill sail construction also referred to as windmill sails, entails each mould element being positioned at right angles to each other, wherein each mould element is placed adjacently of and protruding from another mould element.
  • a rectangular mould for the floor part or wall part is hereby realized, the dimensions of which can be easily adjusted. It will be apparent to the skilled person that other designs, for instance wherein the mould elements are not positioned at right angles to each other, are also possible.
  • each mould element can be used only to manufacture one type of floor part or wall part. This means that a mould element which can be used for a floor part with a first concrete layer which is recessed by 10 centimetres cannot be used for a floor part with a concrete layer which is recessed by 5 centimetres. A custom-made mould element is needed for this purpose.
  • the present invention has for its object to solve or at least reduce the above stated problems. It is a particular object of the invention to provide a mould which can be applied to manufacture floor parts and wall parts of different dimensions.
  • a mould for manufacturing a floor part or wall part with a sandwich structure comprising a plurality of layers comprising:
  • a mould is obtained which enables any practical dimension of the first concrete layer, the insulating layer and the second concrete layer without requiring a large number of different mould elements.
  • the base elements and auxiliary mould elements can be removed from each other in simple manner after manufacture of a floor part or wall part and then be stacked and/or set down again in order to manufacture a subsequent floor part and/or wall part. This greatly reduces the costs of making a floor part or wall part with a sandwich structure of different dimensions because a small number of base mould elements and auxiliary mould elements suffice to make all conceivable dimensions.
  • the flexibility for processing floor parts and/or wall parts with a range of dimensions is also increased.
  • a periphery in which a first concrete layer can be arranged can be formed in simple manner by the number of lower base mould elements. Because the periphery is constructed from individual base mould elements, the periphery can comprise any practical dimensions.
  • the base mould elements preferably take a rectangular form.
  • the base mould elements can hereby be placed adjacently in simple manner so that a complete mould without undesired holes or gaps is realized.
  • auxiliary mould elements By using a first layer of auxiliary mould elements which can be placed on the base mould elements a periphery for an insulating layer and/or second concrete layer can be obtained in simple manner.
  • the auxiliary mould elements can be the same as the base mould elements.
  • the advantage of the auxiliary mould elements which can be placed on the base mould elements is that any desired offset of the insulating layer and/or second concrete layer relative to the first concrete layer can be realized thereby.
  • the auxiliary mould elements can also comprise a profile.
  • the profile can for instance comprise a first and a second part, wherein the second part is placed above the first part relative to the floor part or wall part.
  • the first part can for instance be a periphery for an insulating layer, while the second part forms a periphery for the second concrete layer, wherein the insulating layer and the second concrete layer are optionally offset relative to each other.
  • the base mould elements and auxiliary mould elements are preferably placed on respectively the base and the base mould elements by a robot. This ensures that the base mould elements and auxiliary mould elements are positioned correctly. This also reduces the number of manual operations required.
  • construction elements such as floor parts or wall parts can also be understood to mean outside wall elements, roof edges and roof decking.
  • concrete is also understood to mean alternatives which are possible in the manufacture of floor parts or wall parts. It is thus possible to use a geopolymer instead of concrete.
  • the present invention to a floor part or wall part consisting of a single layer, wherein the single layer has an offset, i.e. comprises a projection, and so forms a variant of a sandwich structure according to the invention. It is further also possible to use the mould according to the invention with the already known mould elements.
  • the mould further comprises a second layer of auxiliary mould elements, wherein the second layer of auxiliary mould elements can be placed mutually adjacently on the first layer of auxiliary mould elements for the purpose of forming a periphery for a second concrete layer arranged above the first concrete layer and insulating layer.
  • the second layer of auxiliary mould elements enables an offset of the second concrete layer relative to the insulating layer to be realized.
  • a floor part or wall part wherein the first concrete layer, the insulating layer and the second concrete layer are all offset relative to each other by a desired distance can hereby be manufactured in simple manner.
  • At least one of the base mould elements and/or auxiliary mould elements comprises an upper plate which is movable toward the base during use and which is configured to provide a clearance for the purpose of releasing the floor part and/or the wall part.
  • the upper plate is an upper part of the base mould element.
  • the upper plate according to the invention is preferably displaceable relative to the (remaining) base mould element, such that a clearance is created between the base mould element and the floor part or wall part. This simplifies the so-called releasing of the floor part or wall part.
  • the advantage of the upper plate is that pouring onto the base mould part or auxiliary mould part can be done in simple manner because this can then also be removed in simple manner.
  • the upper plate is preferably moveable toward the base and/or the underside of the base mould element or auxiliary mould element by means of a moving mechanism.
  • the upper plate is moveable in any case partially in a directional component toward the base.
  • This has the advantage that when the floor part has been manufactured and an insulating layer and/or second concrete layer rests on the base mould elements, a clearance is created between the base mould element and the insulating layer and/or the second concrete layer.
  • the base mould element can be removed from the base and the floor element and/or the wall element can be released from the base in simple manner.
  • an upper plate which is moveable toward the base is the same as an upper plate which is moveable toward the underside of the base mould element and/or the auxiliary mould element.

In this way an overhanging part of the floor part or wall part can be manufactured in simple manner.
  • the base mould element and/or the auxiliary mould element comprises a pouring position and a releasing position, wherein in the releasing position the upper plate is moved toward the base such that an effective height of the base mould element and/or the auxiliary mould element is lower in the releasing position than in the pouring position.
  • the effective height must be understood to mean the height between the underside of the base mould element or auxiliary mould element and the upper wall of the upper plate. Because the effective height differs in the pouring position and the releasing position, a clearance between the base mould element and the floor part and/or the wall part can be obtained in simple manner after manufacture of the floor part and/or the wall part. This facilitates the removal of the base mould elements and the floor part and/or wall part from the base.
  • the effective height of the base mould element and/or the auxiliary mould element is at least 1 millimetre, preferably at least 3 millimetres, more preferably at least 5 millimetres and most preferably at least 10 millimetres lower in the releasing position than in the pouring position.
  • the upper plate is moveable toward the base by means of an obliquely descending surface between the upper plate and the rest of the base element and/or the auxiliary mould element.
  • the oblique surface preferably descends as seen from the floor part and/or the wall part.

  • the pulling movement can for instance be realized with an eccentric.
  • the obliquely descending surface can be deemed part of the moving mechanism.
  • a wedge is provided between the upper plate and the rest of the base mould element and/or the auxiliary mould element, such that when the wedge is pulled out, the base mould element and/or the auxiliary mould element can be moved from the pouring position to the releasing position.
  • the base mould element and/or the auxiliary mould element preferably comprises a pivoting connection between the upper plate and the rest of the base mould element and/or the auxiliary mould element, so that the upper plate is moved toward the base after the wedge is pulled out by the pivoting movement.
  • the wedge can be deemed part of the moving mechanism.
  • the mould further comprises an elastic element arranged between the upper plate and the rest of the base mould element and/or the auxiliary mould element, wherein the upper plate can be moved from the pouring position to the releasing position by compression of the elastic element.
  • the elastic element is made from elastic material.
  • An example of elastic material is rubber, for instance sponge rubber, or an elastic plastic.
  • An advantage of rubber is that it has a closed structure, whereby no (cement) slurry is absorbed in the base mould element and/or the auxiliary mould element.
  • Sponge rubber further has the advantage that it is extra flexible and thereby springs back readily.
  • the elastic element can be deemed part of the moving mechanism.
  • An advantage of the elastic element is that the base mould element and/or the auxiliary mould element can be moved from the pouring position to the releasing position in simple manner by compression of the elastic element.

  • the advantage of the pulling element is that it can be easily applied in combination with a robot system which can move the base mould element and/or the auxiliary mould element from the pouring position to the releasing position by means of a simple pulling movement.
  • pulling element must also be understood to mean a pushing element, wherein the elastic element is compressed and the upper plate is moved from the pouring position to the releasing position by pushing in the pulling element. What is important is that a relative movement of the pulling element relative to the upper plate and the rest of the base mould element and/or the auxiliary mould element takes place.
  • the pulling element can be deemed part of the moving mechanism.
  • the pulling element can also be connected to the rest of the base mould element and/or the auxiliary mould element by means of a screw connection.
